Analysis and Development of Phenomenological Models for the Relative Biological Effectiveness in Proton Therapy
(Doctoral thesis, 2019-08-23)Proton therapy is undergoing a rapid development making it increasingly popular as a treatment of cancer. Protons interact differently with the tissue compared to conventional radiation therapy with photons, resulting in ... -
Aspects of Electron Dynamics in Atoms Exposed to Single Cycle Electromagnetic Pulses
(Doctoral thesis, 2018-06-29)This thesis covers the topic in atomic physics: Interaction of a strong external field with Rydberg hydrogen atom. In three scientific publications, we have targeted physical processes such as the field ionization in the ... -
Auroral imaging as a tracer of global magnetospheric dynamics
(Doctoral thesis, 2010-11-12) -
Autonomic Operation of a Large High Performance On-Line Compute Cluster
(Doctoral thesis, 2015-12-10)A High-Level Trigger (HLT) system is composed of both hardware and software. Designing the physical layout of the cluster mainly concerns the hardware; node distribution, network layout, estimation of power requirements, ... -
Characterising Mesoscale Fast Flow Channels in the Polar Cap Ionosphere
(Doctoral thesis, 2021-01-22)The large-scale ionospheric convection that circulates in the high-latitude polar caps was initially assumed to be a smooth, laminar flow. However, it has now come to light that this is an oversimplified understanding of ... -
Characterization and application of 3D silicon microdosimeters
(Doctoral thesis, 2020-12-11)The effect of ionizing radiation on biological matter differs significantly between the various types of radiation. For the same amount of absorbed energy, some forms of radiation are much more effective in inducing ... -
Charged Higgs boson searches and SemiConductor Tracker commissioning for the ATLAS experiment
(Doctoral thesis, 2007-06-21)The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of four major experiments presently being installed at the upcoming Large Hadron Collider (LHC) at the European Centre for Nuclear Research (CERN) outside Geneva. In ... -
Charged Particle Lithography for the Fabrication of Nanostructured Optical Elements
(Doctoral thesis, 2018-08-31)This thesis work focuses on nanostructured optical elements for light and matter waves that have been fabricated using helium ion beam lithography and electron beam lithography. The motivation of this thesis has been to ... -
CO2-Foams for Enhanced Oil Recovery and CO2 Storage
(Doctoral thesis, 2019-03-01)Human prosperity, economic growth and energy supply have shown a strong positive correlation from the start of the industrial revolution until the present. During the 20th century, cheap and reliable energy from fossil ... -

Correlated ionization processes in atoms and molecules
(Doctoral thesis; Peer reviewed, 2013-09-27)This thesis is composed of five scientific papers written between 2009 and 2013. The focus of this work is on various photo-ionization processes in small atoms and molecules. The strong field phenomenon called “atomic ... -
D0-electron correlations in p–Pb collisions at \(\sqrt{s_{\rm{NN}}}\) = 5.02 TeV
(Doctoral thesis, 2017-04-21)In collisions of lead nuclei at the Large Hadron Collider (LHC) at CERN, a state of matter called Quark-Gluon Plasma (QGP) is formed, where quarks and gluons are no longer confined into hadrons. Heavy-flavour quarks, i.e., ... -
Decontamination of persistent organic pollutants in fishmeal and fish oil. Process optimization and modeling
(Doctoral thesis, 2011-10-07)Persistent organic pollutants (POPs) are fat soluble chemical substances that persist in the environment and bioaccumulate in the food chain. Through long-range environmental transportation by air, water and migratory ... -
Design and Implementation of a High-Speed Readout and Control System for a Digital Tracking Calorimeter for proton CT
(Doctoral thesis, 2021-02-18)Particle therapy, a non-invasive technique for treating cancer using protons and light ions, has become more and more common. For example, a particle treatment facility is currently being built, in Bergen, Norway. Proton ... -
